VALVE.

Application filed November 26, 1920. Serial No. 426,527..

ple and improved construction, whereby a reserve supply of liquid ismade available for use when the main supply in the tank has beenexhausted.

In the accompanying drawing, Fig. 1 is a vertical sectional view of aportion of a gasoline tank having an improved reserve supply valveconstructed in accordance with my invention; and Fig. 2 is a verticalsectional view similar to Fig. 1 showing the valve in position toutilize the reserve supply of gasoline.

In the drawing, the numeral 2 designates a gasoline tank which maysuitably be the ordinary feed tank of an automobile. In the bottom ofthe tank 2 is formed a boss 3 which is screw-threaded to receive thethreaded upper end of a fixed T-shaped outlet tube 4 having a branchconnection 5 screw-threaded at 6 for attachment-to the usual gasolinesupply line. The lower end of the outlet tube 4 is screw-threaded at 7to receive a cap 8 within which is a suitable packing ring 9 whichprevents the escape of liquid from the lower end of the tube 4.

A tube 10 of proper diameter to fit tightly but slidably within thefixed tube 4 extends through the tube 4 and into the tank 2, and carriesat its lower end a stop cock 11. The tube 10 also carries a stop member12, suitably a disc or washer, which limits the downward movement of thetube 10. Just below the stop member12 the tube 10 is provided with anopening 13 and below the opening 13 is another and longer opening 14which communicates with the branch connection 5. It will be observedthat the opening 14 communicates with the branch 5 in all positions ofthe tube 10. V

In the normal operation of the gasoline tank the valve is inthe positionshown in in Fig. 1. The gasoline enters the upper end of the tube 10 andthence passes through the opening 14 and the branch 5. The portion ofthe tube 10 below the opening 14 serves as a trap for sediment, whichmay be removed from time to time through the stop cook 11. The stop cockalso provides convenient means for drawing off a part or all of thegasoline from the tank. V

WVhen the levelof the gasoline in the tank descends to the level of theupper end of the tube 10 it will cease to flow and warning will thus begiven that the tank is nearly empty. In order to make use of the reservesupply of gasoline the tube 10 is pushed up into the position showninFig. 2. The gasoline then enters through the opening 13 and passesoutthrough the opening 14 and the branch 5 as before, the elongatedshape of the opening 14, keeping the tube in communication with thebranch 5.

As shown, the opening 13 in the upper position of the valve as shown inFig. 2, is slightly above the bottom of the tank'2.

Thus when the reserve supply of gasoline is 7 almost exhausted the flowwill again stop, but a small amount of gasoline will still remain in thetank and may be made avail able by pulling out the tube 10 slightly, soas to lower the opening 13 without drawing it down below the bottom ofthe tank. I thus provide for warning the driver of the automobile at twoseparate times of the fact that his tank is nearly empty. While I haveshown and described a preferred embodiment of'my invention, it is to beunderstood that various changes may be made and that my invention islimited only by the scope of the appended claims.

I claim as my invention I 1. A valve for liquid receptacles comprising atubular member'having a lateral outlet, a tube mounted slidably withinthe said tubular member and having both ends extending beyond the saidmember, and means for limiting the sliding movement of the said innertube, the said inner tube being provlded with two openings, one of thesaid openings being in constant communication and provided with alateral outlet, a tube cured to the lower end of the said inner tube,the said inner tube being provided with two openings, one of the saidopenings being disposed adjacent to the said said stop member and theother said opening being disposed below the said first named opening andin communication with the said lateral outlet.

3. A valve for liquid receptacles comprising a tubular member adapted tobe screwthreaded into the bottom of a tank and provided with a lateraloutlet, a tube slidprovided with two openings, one of the said openingsbeing disposed adjacent to the said stop member and the other saidopening being of elongated form and in constant communication with thesaid branch outlet.

4. The combination with a gasoline tank, and a chambered supply pipecoupling connected into and communicating with the bottom of said tank,of a supply pipe section mounted in and adjustable endwise through saidcoupling with its upper end projecting into said tank and its lower endextending below said coupling, said supply pipe section having a lateralport communicating with the chamber of said coupling, and a drain valvein the lower end of said supply pipe section. I

In testimony whereof, I the said WILLIAM H. MORRIS have hereunto set myhand.
